Well where do I start? I have had all my modifications since December except a CAI swap 4 weeks ago and also an exhaust swap from NIsmo to invidia also for 4 weeks ago. Well after January I started getting an engine light everytime the car was at idle for more than 10 minutes or so and everytime I would have to take it to the dealer and have it reset. Dealer claimes it was the computer thining the car was running lean due to the cats and nitrous lines but it wasnt so they offered to reset it for free eveytime. They claimed it is an emissions code. Well after that in March I had a plenum installed and found that the emission hose under the intake tube wasnt plugged. I thought that was the cause and after that even if I had the car running at idle no lights.

Well today I was waiting for my wife for like 10-12 minutes in a parking lot at idle and when I started going the light came on. So I dont know if its the same thing or what. Engine feels fine except the rough idle that i get occasionally but im concerned. Im sure if it was somehting serious I could feel soemthing wrong but engine revs fine and everything.

I checked th egas cap and it came right off after kess than half a turn so I dont know if it was that I didnt click it or what but im so concerned.

Sorry to bother you guys but this is my 3rd Z and I had issues with all of them except this one till know possibly.

Please let me know, at least tell me if you think its serious! My mods are in my signature.

 

Well today the bumper was sold and when they removed it we found my CAI AEM filter dangling from th elast tip to the actual CAI tube basiucally 95% off. COuld this have been it?
